FIELD OF THE INVENTION

The present invention features combination compositions and methods of treating Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) mediated diseases related thereto.

BACKGROUND OF THE INVENTION

Cystic fibrosis (CF) is a recessive genetic disease that affects approximately 30,000 children and adults in the United States and approximately 30,000 children and adults in Europe. Despite progress in the treatment of CF, there is no cure.

In patients with CF, mutations in CFTR endogenously expressed in respiratory epithelia leads to reduced apical anion secretion causing an imbalance in ion and fluid transport. The resulting decrease in anion transport contributes to enhanced mucus accumulation in the lung and the accompanying microbial infections that ultimately cause death in CF patients. In addition to respiratory disease, CF patients typically suffer from gastrointestinal problems and pancreatic insufficiency that, if left untreated, results in death. In addition, the majority of males with cystic fibrosis are infertile and fertility is decreased among females with cystic fibrosis. In contrast to the severe effects of two copies of the CF associated gene, individuals with a single copy of the CF associated gene exhibit increased resistance to cholera and to dehydration resulting from diarrhea—perhaps explaining the relatively high frequency of the CF gene within the population.

Sequence analysis of the CFTR gene of CF chromosomes has revealed a variety of disease causing mutations (Cutting, G. R. et al. (1990) Nature 346:366-369; Dean, M. et al. (1990) Cell 61:863:870; and Kerem, B-S. et al. (1989) Science 245:1073-1080; Kerem, B-S et al. (1990) Proc. Natl. Acad. Sci. USA 87:8447-8451). To date, greater than 1000 disease causing mutations in the CF gene have been identified (http://www.genet.sickkids.on.ca/cftr/app). The most prevalent mutation is a deletion of phenylalanine at position 508 of the CFTR amino acid sequence, and is commonly referred to as ΔF508-CFTR. This mutation occurs in approximately 70% of the cases of cystic fibrosis and is associated with a severe disease.

The deletion of residue 508 in ΔF508-CFTR prevents the nascent protein from folding correctly. This results in the inability of the mutant protein to exit the ER, and traffic to the plasma membrane. As a result, the number of channels present in the membrane is far less than observed in cells expressing wild-type CFTR. In addition to impaired trafficking, the mutation results in defective channel gating. Together, the reduced number of channels in the membrane and the defective gating lead to reduced anion transport across epithelia leading to defective ion and fluid transport. (Quinton, P. M. (1990), FASEB J. 4: 2709-2727). Studies have shown, however, that the reduced numbers of ΔF508-CFTR in the membrane are functional, albeit less than wild-type CFTR. (Dalemans et al. (1991), Nature Lond. 354: 526-528; Denning et al., supra; Pasyk and Foskett (1995), J. Cell. Biochem. 270: 12347-50). In addition to ΔF508-CFTR, other disease causing mutations in CFTR that result in defective trafficking, synthesis, and/or channel gating could be up- or down-regulated to alter anion secretion and modify disease progression and/or severity.

Accordingly, there is a need for novel treatments of CFTR mediated diseases.

DETAILED DESCRIPTION

The present invention provides pharmaceutical formulations and compositions that are useful for treating cystic fibrosis.

I. DEFINITIONS

As used herein, “CFTR” stands for cystic fibrosis transmembrane conductance regulator.

As used herein, “mutations” can refer to mutations in the CFTR gene or the CFTR protein. A “CFTR mutation” refers to a mutation in the CFTR gene, and a “CFTR mutation” refers to a mutation in the CFTR protein. A genetic defect or mutation, or a change in the nucleotides in a gene in general results in a mutation in the CFTR protein translated from that gene.

As used herein, a “ΔF508 mutation” or “F508-del mutation” is a specific mutation within the CFTR protein. The mutation is a deletion of the three nucleotides that comprise the codon for amino acid phenylalanine at position 508, resulting in CFTR protein that lacks this phenylalanine residue.

The term “CFTR gating mutation” as used herein means a CFTR mutation that results in the production of a CFTR protein for which the predominant defect is a low channel open probability compared to normal CFTR (Van Goor, F., Hadida S. and Grootenhuis P., “Pharmacological Rescue of Mutant CFTR function for the Treatment of Cystic Fibrosis”, Top. Med. Chem. 3: 91-120 (2008)). Gating mutations include, but are not limited to, G551D, G178R, S549N, S549R, G551S, G970R, G1244E, S1251N, S1255P, and G1349D.

As used herein, a patient who is “homozygous” for a particular mutation, e.g., ΔF508, has the same mutation on each allele.

As used herein, a patient who is “heterozygous” for a particular mutation, e.g., ΔF508, has this mutation on one allele, and a different mutation on the other allele.

As used herein, the term “CFTR corrector” refers to a compound that increases the amount of functional CFTR protein to the cell surface, resulting in enhanced ion transport.

As used herein, the term “CFTR potentiator” refers to a compound that increases the channel activity of CFTR protein located at the cell surface, resulting in enhanced ion transport.

As used herein, the term “inducing”, as in inducing CFTR activity, refers to increasing CFTR activity, whether by the corrector, potentiator, or other mechanism.

As used herein, the terms “active pharmaceutical ingredient”, “API”, and “therapeutic agent” are used interchangeably to refer to a biologically active compound.

A “patient”, “subject”, or “individual” are used interchangeably and refer to either a human or non-human animal. The term includes mammals such as humans.

As used herein, the term “solvent system” refers to a system comprising an organic solvent capable of dissolving Compound 1 and Compound 2.

As used herein, the term “biological medium” refers to a real or simulated gastrointestinal fluid. A simulated gastrointestinal fluid would be an in vitro gastrointestinal fluid such as, for example, fed state simulated intestinal fluid (FedSIF). A real gastrointestinal fluid would be an in vivo gastrointestinal fluid such as what exists within a patient.

The terms “effective dose” or “effective amount” are used interchangeably herein and refer to that amount that produces the desired effect for which it is administered (e.g., improvement in CF or a symptom of CF or lessening the severity of CF or a symptom of CF). The exact amount will depend on the purpose of the treatment, and will be ascertainable by one skilled in the art using known techniques (see, e.g., Lloyd (1999) The Art, Science and Technology of Pharmaceutical Compounding).

As used herein, the terms “treatment”, “treating”, and the like generally refer to the improvement of CF or its symptoms or lessening the severity of CF or its symptoms in a subject. “Treatment”, as used herein, includes, but is not limited to, the following: increased growth of the subject, increased weight gain, reduction of mucus in the lungs, improved pancreatic and/or liver function, reduced cases of chest infections, and/or reduced instances of coughing or shortness of breath. Improvements in or lessening the severity of any of these conditions can be readily assessed according to standard methods and techniques known in the art.

As used herein, the term “in combination with”, when referring to two or more compounds or agents, means that the order of administration includes the compounds or agents being administered prior to, concurrent with, or subsequent to each other to the patient.

The terms “about” and “approximately”, when used in connection with doses, amounts, or weight percent of ingredients of a composition or a dosage form, mean a dose, amount, or weight percent that is recognized by one of ordinary skill in the art to provide a pharmacological effect equivalent to that obtained from the specified dose, amount, or weight percent. Specifically the term “about” or “approximately” means an acceptable error for a particular value as determined by one of ordinary skill in the art, which depends in part on how the value is measured or determined. In certain embodiments, the term “about” or “approximately” means within 1, 2, 3, or 4 standard deviations. In certain embodiments, the term “about” or “approximately” means within 30%, 25%, 20%, 15%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%, 0.5%, 0.1%, or 0.05% of a given value or range.

As used herein, “Compound 1” and “Cmpd 1” are used interchangeably to refer to the compound (R)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(1-(2,3-dihydroxypropyl)-6-fluoro-2-(1-hydroxy-2-methylpropan-2-yl)-1H-indol-5-yl)cyclopropanecarboxamide. This compound has the structure:

As used herein, “Compound 2” and “Cmpd 2” are used interchangeably to refer to the compound N-[2,4-bis(1,1-dimethylethyl)-5-hydroxyphenyl]-1,4-dihydro-4-oxoquinoline-3-carboxamide. This compound has the structure:

As used herein, the terms “substantially free” and “neat” are used interchangeably to refer to a mixture or material that has a concentration of less than about 1 wt % (e.g., less than about 0.5 wt %, less than about 0.1 wt %, less than about 1000 ppm, or less than about 500 ppm) of another dopant, compound, impurity, or material (e.g., polymer). A dopant, compound, impurity, or material (e.g., polymer) is absent from a mixture or material when that mixture or material is substantially free of the compound, impurity, or material (e.g., polymer). For example, a mixture or dispersion that is substantially free of a polymer has a concentration of less than about 1 wt % (e.g., less than about 0.5 wt %, less than about 0.1 wt %, less than about 1000 ppm, or less than about 500 ppm) of polymer.

As used herein, “glass transition temperature” or “Tg” refer to the temperature below which the physical properties of amorphous materials vary in a manner similar to those of a solid phase (glassy state), and above which amorphous materials behave like liquids (rubbery state).

As used herein, the term “amorphous” refers to a solid material having no long range order in the position of its molecules. Amorphous solids are generally supercooled liquids in which the molecules are arranged in a random manner so that there is no well-defined arrangement, e.g., molecular packing, and no long range order. Amorphous solids are generally isotropic, i.e. exhibit similar properties in all directions and do not have definite melting points. For example, an amorphous material is a solid material having no sharp characteristic crystalline peak(s) in its X-ray power diffraction (XRPD) pattern (i.e., is not crystalline as determined by XRPD). Instead, one or several broad peaks (e.g., halos) appear in its XRPD pattern. Broad peaks are characteristic of an amorphous solid. See, US 2004/0006237 for a comparison of XRPDs of an amorphous material and crystalline material.

As used herein, the term “substantially amorphous” refers to a solid material having little or no long range order in the position of its molecules. For example, substantially amorphous materials have less than about 15% crystallinity (e.g., less than about 10% crystallinity or less than about 5% crystallinity). It is also noted that the term ‘substantially amorphous’ includes the descriptor, ‘amorphous’, which refers to materials having no (0%) crystallinity.

As used herein, the term “dispersion” refers to a disperse system in which one substance, the dispersed phase, is distributed, in discrete units, throughout a second substance (the continuous phase or vehicle). The size of the dispersed phase can vary considerably (e.g. colloidal particles of nanometer dimension, to multiple microns in size). In general, the dispersed phases can be solids, liquids, or gases. In the case of a solid dispersion, the dispersed and continuous phases are both solids. In pharmaceutical applications, a solid dispersion can include a crystalline drug (dispersed phase) in an amorphous polymer (continuous phase); or alternatively, an amorphous drug (dispersed phase) in an amorphous polymer (continuous phase). In some embodiments, a solid dispersion includes the polymer constituting the dispersed phase, and the drug constitute the continuous phase. Or, a solid dispersion includes the drug constituting the dispersed phase, and the polymer constituting the continuous phase.

B. Methods of Preparing a Spray Dried Dispersion Substantially Free of Polymer

Starting from Compound 1 or Compound 2, the amorphous form of Compound 1 or Compound 2 may be prepared by spray drying methods. Spray drying is a process that converts a liquid feed to a dried particulate form. Optionally, a secondary drying process such as fluidized bed drying or vacuum drying may be used to reduce residual solvents to pharmaceutically acceptable levels. Typically, spray drying involves contacting a highly dispersed liquid suspension or solution, and a sufficient volume of hot air to produce evaporation and drying of the liquid droplets. The preparation to be spray dried can be any solution, coarse suspension, slurry, colloidal dispersion, or paste that may be atomized using the selected spray drying apparatus. In one procedure, the preparation is sprayed into a current of warm filtered gas that evaporates the solvent and conveys the dried product to a collector (e.g. a cyclone). The spent gas is then exhausted with the solvent, or alternatively the spent air is sent to a condenser to capture and potentially recycle the solvent. Commercially available types of apparatus may be used to conduct the spray drying. For example, commercial spray dryers are manufactured by Buchi Ltd. And Niro (e.g., the PSD line of spray driers manufactured by Niro) (see, US 2004/0105820; US 2003/0144257).

Techniques and methods for spray drying may be found in Perry's Chemical Engineering Handbook, 6th Ed., R. H. Perry, D. W. Green & J. O. Maloney, eds.), McGraw-Hill book co. (1984); and Marshall “Atomization and Spray-Drying” 50, Chem. Eng. Prog. Monogr. Series 2 (1954). All three references are incorporated herein in their entirety by reference.

Removal of the solvent may require a subsequent drying step, such as tray drying, fluid bed drying (e.g., from about room temperature to about 100° C.), vacuum drying, microwave drying, rotary drum drying or biconical vacuum drying (e.g., from about room temperature to about 200° C.).

In one embodiment, the solid dispersion is fluid bed dried.

In one process, the solvent includes a volatile solvent, for example a solvent having a boiling point of less than about 100° C. In some embodiments, the solvent includes a mixture of solvents, for example a mixture of volatile solvents or a mixture of volatile and non-volatile solvents. Where mixtures of solvents are used, the mixture can include one or more non-volatile solvents, for example, where the non-volatile solvent is present in the mixture at less than about 15%, e.g., less than about 12%, less than about 10%, less than about 8%, less than about 5%, less than about 3%, or less than about 2%.

In some processes, solvents are those solvents where Compound 1 and Compound 2 have solubilities of at least about 10 mg/ml, (e.g., at least about 15 mg/ml, 20 mg/ml, 25 mg/ml, 30 mg/ml, 35 mg/ml, 40 mg/ml, 45 mg/ml, 50 mg/ml, or greater). In other processes, solvents include those solvents where Compound 1 has a solubility of at least about 20 mg/ml.

Exemplary solvents that could be tested include acetone, cyclohexane, dichloromethane, N,N-dimethylacetamide (DMA), N,N-dimethylformamide (DMF), 1,3-dimethyl-2-imidazolidinone (DMI), dimethyl sulfoxide (DMSO), dioxane, ethyl acetate, ethyl ether, glacial acetic acid (HAc), methyl ethyl ketone (MEK), N-methyl-2-pyrrolidinone (NMP), methyl tert-butyl ether (MTBE), tetrahydrofuran (THF), pentane, acetonitrile, methanol, ethanol, isopropyl alcohol, isopropyl acetate, DCM, and toluene. Exemplary co-solvents include acetone/DMSO, acetone/DMF, acetone/water, MEK/water, THF/water, dioxane/water. In a two solvent system, the solvents can be present in of from about 0.1% to about 99.9%. In some preferred embodiments, water is a co-solvent with acetone where water is present from about 0.1% to about 15%, for example about 9% to about 11%, e.g., about 10%. In some preferred embodiments, water is a co-solvent with MEK where water is present from about 0.1% to about 15%, for example about 9% to about 11%, e.g., about 10%. In some embodiments the solvent system includes three solvents. In instances where amorphous Compound 1 is a component of a solid amorphous dispersion, preferred solvents dissolve both Compound 1 and the polymer. Suitable solvents include those described above, for example, MEK, DCM, water, methanol, IPA, and mixtures thereof.

The particle size and the temperature drying range may be modified to prepare an optimal solid dispersion. As would be appreciated by skilled practitioners, a small particle size would lead to improved solvent removal. Applicants have found however, that smaller particles can lead to fluffy particles that, under some circumstances do not provide optimal solid dispersions for downstream processing such as tableting. At higher temperatures, crystallization or chemical degradation of Compound 1 or Compound 2 may occur. At lower temperatures, a sufficient amount of the solvent may not be removed. The methods herein provide an optimal particle size and an optimal drying temperature.

A spray dried dispersion substantially free of polymer of the present embodiment may optionally include a surfactant. A surfactant or surfactant mixture would generally decrease the interfacial tension between the solid dispersion and an aqueous medium. An appropriate surfactant or surfactant mixture may also enhance aqueous solubility and bioavailability of Compound 1 or Compound 2 from a solid dispersion. The surfactants for use in connection with the present invention include, but are not limited to, sorbitan fatty acid esters (e.g., Spans®), polyoxyethylene sorbitan fatty acid esters (e.g., Tweens®), sodium lauryl sulfate (SLS), sodium dodecylbenzene sulfonate (SDBS) dioctyl sodium sulfosuccinate (Docusate), dioxycholic acid sodium salt (DOSS), sorbitan monostearate, sorbitan tristearate, hexadecyltrimethyl ammonium bromide (HTAB), sodium N-lauroylsarcosine, sodium oleate, sodium myristate, sodium stearate, sodium palmitate, gelucire 44/14, ethylenediamine tetraacetic acid (EDTA), vitamin E d-alpha tocopheryl polyethylene glycol 1000 succinate (TPGS), lecithin, MW 677-692, glutanic acid monosodium monohydrate, labrasol, PEG 8 caprylic/capric glycerides, transcutol, diethylene glycol monoethyl ether, solutol HS-15, polyethylene glycol/hydroxystearate, taurocholic acid, pluronic F68, pluronic F108, and pluronic F127 (or any other polyoxyethylene-polyoxypropylene co-polymers (Pluronics®) or saturated polyglycolized glycerides (Gelucirs®)). Specific example of such surfactants that may be used in connection with this invention include, but are not limited to, Span 65, Span 25, Tween 20, Capryol 90, Pluronic F108, sodium lauryl sulfate (SLS), vitamin E TPGS, pluronics and copolymers. SLS is generally preferred.

The amount of the surfactant (e.g., SLS) relative to the total weight of the solid dispersion may be between 0.1-15%. Preferably, it is from about 0.5% to about 10%, more preferably from about 0.5 to about 5%, e.g., about 0.5 to 4%, about 0.5 to 3%, about 0.5 to 2%, about 0.5 to 1%, or about 0.5%.

In certain embodiments, the amount of the surfactant relative to the total weight of the solid dispersion is at least about 0.1%, preferably at least about 0.5%. In these embodiments, the surfactant would be present in an amount of no more than about 15%, and preferably no more than about 12%, about 11%, about 10%, about 9%, about 8%, about 7%, about 6%, about 5%, about 4%, about 3%, about 2% or about 1%. An embodiment wherein the surfactant is in an amount of about 0.5% by weight is preferred.

Candidate surfactants (or other components) can be tested for suitability for use in the invention in a manner similar to that described for testing polymers.

C. Beneficial Properties of Spray Dried Dispersions Substantially Free of Polymer

The present invention features compositions where properties such as physical stability and dissolution rates are improved when one therapeutic agent is in the presence of another. For example, Compound 1 and Compound 2 in the presence of each other unexpectedly demonstrate improved properties over individual formulations. FIG. 9 depicts fluid stability of Compound 1 in fed state simulated intestinal fluid (FedSIF). The set of bars labeled Neat 1:1 coSDD is the neat coSDD of Compound 1 and Compound 2 substantially free of polymer featured in the present invention. Along the y axis is concentration of Compound 1 in mg/ml and each bar along the x axis represents time: 0.5 h, 1 h, 3 h, 5 h, 29 h, and 72 h.

The stability of Compound 1 in the neat coSDD of Compound 1 and Compound 2 of the present invention over 72 h compared to the set of bar graphs labeled Compound 1 SDD (50% HPMCAS), which is Compound 1 alone in a 50% by weight SDD with the polymer HPMCAS. Achievement of such stability in the absence of a polymer is surprising because a polymer is considered necessary in the art to achieve stable spray dried dispersions. The fact that greater and more consistent stability is achieved is truly unexpected. Such spray dried dispersions would be advantageous for high drug load formulations because more drug could be formulated without the additional volume of a polymer.

The same unexpected phenomena exist for Compound 2 as can be seen in the analogous set of experiments in FIG. 10. FIG. 10 depicts fluid stability of Compound 2 in compositions of the present invention in FedSIF. The set of bars labeled Neat 1:1 coSDD is the neat coSDD of Compound 1 and Compound 2 substantially free of polymer featured in the present invention.

As with Compound 1 in FIG. 9, one can see the increased stability of Compound 2 in the neat coSDD of Compound 1 and Compound 2 of the present invention over 72 h compared to the set of bar graphs labeled Compound 2 SDD (20% HPMCAS), which is Compound 2 alone in a 20% by weight SDD with the polymer HPMCAS.

In addition to increased physical stability in solution, Compound 2 in the compositions of the present invention have unexpectedly increased dissolution rates. FIG. 11 depicts the results of dissolution rate experiments for a tablet comprising the neat co-spray dried dispersion of Compound 1 and Compound 2 (circles) and a tablet comprising a spray dried dispersion of Compound 2 alone and polymer (triangles). The neat co-spray dried dispersion of Compound 1 and Compound 2 demonstrates a significant increase in dissolution rates for Compound 2 over those of Compound 2 in the absence of Compound 1. The increased dissolution rate translates into statistically significant increases in exposure in vivo for Compound 2. Table 1 shows dog pK results for Compound 2 in a tablet of the neat coSDD of Compound 1 and Compound 2 of the present invention relative to a tablet of Compound 2 alone.

TABLE 1 Relative Comparison Geometric Lower Upper (Ratio) Property Mean Ratio 90% 90% Compound Neat coSDD/ Cmax wt 172.93 121.95 245.20 2 Individual norm Tablets AUC wt 146.73 101.19 212.75 norm

When Compound 2 is in the presence of Compound 1, the maximum concentration and area under the curve increases by 73% and 47%, respectively, relative to Compound 2 alone.

Without being bound by theory, the inventors submit that Compound 1 in the presence of Compound 2 unexpectedly interacts to such an extent that even when in media they do not behave as completely individual species. FIG. 1 depicts an XRPD pattern of a 1:1 neat co-spray dried dispersion of Compound 1 and Compound 2 as an amorphous entity. FIG. 2 depicts a differential scanning calorimetry (DSC) trace of a 1:1 neat coSDD of Compound 1 and Compound 2 showing one transition at a Tg of 124° C. Interestingly, FIG. 3 depicts the solid state NMR spectra of a 1:1 Compound 1 to Compound 2 neat co-spray dried dispersion showing spin diffusion interactions between protons on the different compounds, respectively. FIG. 6 depicts an XRPD pattern of a 1:3 neat coSDD of Compound 1 and Compound 2 as an amorphous entity. FIG. 7 depicts a differential scanning calorimetry (DSC) trace of a 1:3 neat coSDD of Compound 1 and Compound 2 showing one transition at a Tg of 155° C.

III. SPRAY DRIED DISPERSIONS COMPRISING AMORPHOUS THERAPEUTIC AGENTS A. Spray Dried Dispersions

Unlike the previously described embodiments which were substantially free of polymer, the spray dried dispersions of the present embodiment may comprise a polymer. Starting from Compound 1 or Compound 2, the amorphous form of Compound 1 or Compound 2 may be prepared by the spray dry methods described previously except that a polymer may be present.

Solid dispersions including amorphous Compound 1 and Compound 2, and a polymer (or solid state carrier) also are included herein. For example, Compound 1 and Compound 2 are present as amorphous compounds as a component of a solid amorphous dispersion. The solid amorphous dispersion, generally includes Compound 1 and Compound 2 and a polymer. Exemplary polymers include cellulosic polymers such as HPMC, HPMCAS, or pyrrolidone containing polymers such as PVP/VA. In some embodiments, the solid amorphous dispersion includes one or more additional excipients, such as a surfactant.

In one embodiment, a polymer is able to dissolve in aqueous media. The solubility of the polymers may be pH independent or pH dependent. The latter include one or more enteric polymers. The term “enteric polymer” refers to a polymer that is preferentially soluble in the less acidic environment of the intestine relative to the more acid environment of the stomach, for example, a polymer that is insoluble in acidic aqueous media but soluble when the pH is above 5-6. An appropriate polymer should be chemically and biologically inert. In order to improve the physical stability of the solid dispersions, the glass transition temperature (Tg) of the polymer should be as high as possible. For example, polymers have a glass transition temperature at least equal to or greater than the glass transition temperature of the drug (i.e., Compound 1). Other polymers have a glass transition temperature that is within about 10 to about 15° C. of the drug (i.e., Compound 1). Examples of suitable glass transition temperatures of the polymers include at least about 90° C., at least about 95° C., at least about 100° C., at least about 105° C., at least about 110° C., at least about 115° C., at least about 120° C., at least about 125° C., at least about 130° C., at least about 135° C., at least about 140° C., at least about 145° C., at least about 150° C., at least about 155° C., at least about 160° C., at least about 165° C., at least about 170° C., or at least about 175° C. (as measured under dry conditions). Without wishing to be bound by theory, it is believed that the underlying mechanism is that a polymer with a higher Tg generally has lower molecular mobility at room temperature, which can be a crucial factor in stabilizing the physical stability of the amorphous solid dispersion.

Additionally, the hygroscopicity of the polymers should be as low, e.g., less than about 10%. For the purpose of comparison in this application, the hygroscopicity of a polymer or composition is characterized at about 60% relative humidity. In some preferred embodiments, the polymer has less than about 10% water absorption, for example less than about 9%, less than about 8%, less than about 7%, less than about 6%, less than about 5%, less than about 4%, less than about 3%, or less than about 2% water absorption. The hygroscopicity can also affect the physical stability of the solid dispersions. Generally, moisture adsorbed in the polymers can greatly reduce the Tg of the polymers as well as the resulting solid dispersions, which will further reduce the physical stability of the solid dispersions as described above.

In one embodiment, the polymer is one or more water-soluble polymer(s) or partially water-soluble polymer(s). Water-soluble or partially water-soluble polymers include but are not limited to, cellulose derivatives (e.g., hydroxypropylmethylcellulose (HPMC), hydroxypropylcellulose (HPC)) or ethylcellulose; polyvinylpyrrolidones (PVP); polyethylene glycols (PEG); polyvinyl alcohols (PVA); acrylates, such as polymethacrylate (e.g., Eudragit® E); cyclodextrins (e.g., β-cyclodextin) and copolymers and derivatives thereof, including for example PVP-VA (polyvinylpyrollidone-vinyl acetate).

In some embodiments, the polymer is hydroxypropylmethylcellulose (HPMC), such as HPMC E50, HPMC E15, or HPMC E3.

As discussed herein, the polymer can be a pH-dependent enteric polymer. Such pH-dependent enteric polymers include, but are not limited to, cellulose derivatives (e.g., cellulose acetate phthalate (CAP)), hydroxypropyl methyl cellulose phthalates (HPMCP), hydroxypropyl methyl cellulose acetate succinate (HPMCAS), carboxymethylcellulose (CMC) or a salt thereof (e.g., a sodium salt such as (CMC-Na)); cellulose acetate trimellitate (CAT), hydroxypropylcellulose acetate phthalate (HPCAP), hydroxypropylmethyl-cellulose acetate phthalate (HPMCAP), and methylcellulose acetate phthalate (MCAP), or polymethacrylates (e.g., Eudragit® S). In some embodiments, the polymer is hydroxypropyl methyl cellulose acetate succinate (HPMCAS). In some embodiments, the polymer is hydroxypropyl methyl cellulose acetate succinate HG grade (HPMCAS-HG).

In yet another embodiment, the polymer is a polyvinylpyrrolidone co-polymer, for example, a vinylpyrrolidone/vinyl acetate co-polymer (PVP/VA).

In embodiments where Compound 1 forms a solid dispersion with a polymer, for example with an HPMC, HPMCAS, or PVP/VA polymer, the amount of polymer relative to the total weight of the solid dispersion ranges from about 0.1% to 99% by weight. Unless otherwise specified, percentages of drug, polymer and other excipients as described within a dispersion are given in weight percentages. The amount of polymer is typically at least about 20%, and preferably at least about 30%, for example, at least about 35%, at least about 40%, at least about 45%, or about 50% (e.g., 49.5%). The amount is typically about 99% or less, and preferably about 80% or less, for example about 75% or less, about 70% or less, about 65% or less, about 60% or less, or about 55% or less. In one embodiment, the polymer is in an amount of up to about 50% of the total weight of the dispersion (and even more specifically, between about 40% and 50%, such as about 49%, about 49.5%, or about 50%). HPMCAS is available in a number of varieties, including AS-LF, AS-MF, AS-HF, AS-LG, AS-MG, AS-HG. Each of these grades varies with the percent substitution of acetate and succinate.

In some embodiments, Compound 1 or Compound 2, and polymer are present in roughly equal amounts, for example each of the polymer and the drug make up about half of the percentage weight of the dispersion. For example, the polymer is present in about 49.5% and Compound 1 or Compound 2 is present in about 50%. In another embodiment, Compound 1 or Compound 2 are present in an amount greater than half of the percentage weight of the dispersions. For example, the polymer is present in about 20% and Compound 1 or Compound 2 is present in about 80%.

In some embodiments, Compound 1 or Compound 2 and the polymer combined represent 1% to 20% w/w total solid content of the non-solid dispersion prior to spray drying. In some embodiments, Compound 1 or Compound 2 and the polymer combined represent 5% to 15% w/w total solid content of the non-solid dispersion prior to spray drying. In some embodiments, Compound 1 or Compound 2 and the polymer combined represent about 11% w/w total solid content of the non-solid dispersion prior to spray drying.

In some embodiments, the dispersion further includes other minor ingredients, such as a surfactant (e.g., SLS). In some embodiments, the surfactant is present in less than about 10% of the dispersion, for example less than about 9%, less than about 8%, less than about 7%, less than about 6%, less than about 5%, less than about 4%, less than about 3%, less than about 2%, about 1%, or about 0.5%.

In embodiments including a polymer, the polymer should be present in an amount effective for stabilizing the solid dispersion. Stabilizing includes inhibiting or preventing, the crystallization of Compound 1 or Compound 2. Such stabilizing would inhibit the conversion Compound 1 or Compound 2 from amorphous to crystalline form. For example, the polymer would prevent at least a portion (e.g., about 5%, about 10%, about 15%, about 20%, about 25%, about 30%, about 35%, about 40%, about 45%, about 50%, about 55%, about 60%, about 65%, about 70%, about 75%, or greater) of Compound 1 or Compound 2 from converting from an amorphous to a crystalline form. Stabilization can be measured, for example, by measuring the glass transition temperature of the solid dispersion, measuring the rate of relaxation of the amorphous material, or by measuring the solubility or bioavailability of Compound 1 or Compound 2.

Suitable polymers for use in combination with Compound 1 or Compound 2, for example to form a solid dispersion such as an amorphous solid dispersion, should have one or more of the following properties:

The glass transition temperature of the polymer should have a temperature of no less than about 10-15° C. lower than the glass transition temperature of Compound 1 or Compound 2. In some instances, the glass transition temperature of the polymer is greater than the glass transition temperature of Compound 1 or Compound 2, and in general at least 50° C. higher than the desired storage temperature of the drug product. For example, at least about 100° C., at least about 105° C., at least about 105° C., at least about 110° C., at least about 120° C., at least about 130° C., at least about 140° C., at least about 150° C., at least about 160° C., at least about 160° C., or greater.

The polymer should have similar or better solubility in solvents suitable for spray drying processes relative to that of Compound 1 or Compound 2. In some embodiments, the polymer will dissolve in one or more of the same solvents or solvent systems as Compound 1 or Compound 2.

The polymer, when combined with Compound 1 or Compound 2, for example in a solid dispersion or in a liquid suspension, should increase the solubility of Compound 1 in aqueous and physiologically relative media either relative to the solubility of Compound 1 or Compound 2 in the absence of polymer or relative to the solubility of Compound 1 or Compound 2 when combined with a reference polymer. For example, the polymer could increase the solubility of amorphous Compound 1 or Compound 2 by reducing the amount of amorphous Compound 1 or Compound 2 that converts to crystalline Compound 1 or Compound 2, either from a solid amorphous dispersion or from a liquid suspension.

The polymer should decrease the relaxation rate of the amorphous substance.

The polymer should increase the physical and/or chemical stability of Compound 1 or Compound 2.

The polymer should improve the manufacturability of Compound 1 or Compound 2.

The polymer should improve one or more of the handling, administration or storage properties of Compound 1 or Compound 2.

The polymer should not interact unfavorably with other pharmaceutical components, for example excipients.

The suitability of a candidate polymer (or other component) can be tested using the spray drying methods (or other methods) described herein to form an amorphous composition. The candidate composition can be compared in terms of stability, resistance to the formation of crystals, or other properties, and compared to a reference preparation, e.g., a preparation of neat amorphous Compound 1 or Compound 2. For example, a candidate composition could be tested to determine whether it inhibits the time to onset of solvent mediated crystallization, or the percent conversion at a given time under controlled conditions, by at least 50%, 75%, or 100% as well as the reference preparation, or a candidate composition could be tested to determine if it has improved bioavailability or solubility relative to crystalline Compound 1 or Compound 2.

In some implementations, the cellulose polymer of the first mixture is HPMC.

In some implementations, the first mixture comprises a ratio of HPMC to Compound 1 ranging from about 1:10 to about 1:1 by weight. For example, the ratio of HPMC to Compound 1 is from about 1:3 to about 1:5 (e.g., about 1:4) by weight.

In some implementations, the first mixture further comprises a solvent, and the solvent comprises a polar organic solvent. Examples of polar organic solvents include methylethyl ketone, THF, methanol, DCM, or IPA, or any combination thereof, such as for example, a DCM/methanol mixture. In other examples, the solvent further comprises water. In other examples, the solvent further comprises water. For instance, the solvent could be methylethyl ketone/water, THF/water, methanol/water, or methylethyl ketone/water/IPA.

Such filtering can be accomplished using any suitable filter media having a suitable pore size (e.g., 20 μm or less). Likewise, the second mixture may also be filtered before it is forced through the nozzle.

Some implementations further comprise drying the first spray dried dispersion, the second spray dried dispersion or both. For example, the spray dried dispersion, i.e., the first spray dried dispersion, the second spray dried dispersion, or both, is dried under reduced pressure. In other examples, the spray dried dispersion is dried at a temperature of from about 30° C. to about 60° C.

FIGS. 12 and 13 show that the same surprising stability of Compound 1 in the presence of Compound 2 is present even in a blend of two separate spray dried dispersion. FIGS. 12 and 13 depict the Compound 1 crystallization kinetics under 75% relative humidity and 80° C. and 70° C., respectively. Triangles represent a tablet formulation of a blend of the two separate spray dried dispersions of Compound 1 and Compound 2. Circles represent the same tablet formulation just lacking Compound 2. Squares represent the separate spray dried dispersion of Compound 1. Comparing the tablet blend formulation to the Compound 2 free tablet formulation, one can see that Compound 1 is significantly more stable towards crystallization in the presence of Compound 2. Compound 1 is also more stable in the tablet formulation with Compound 2 than in the separate spray dried dispersion of Compound 1.

One explanation for this phenomenon is shown in FIG. 14. As was seen in the co-spray dried dispersion of Compound 1 and Compound 2 substantially free of polymer (FIG. 3A), a blend of two spray dried dispersions comprising Compound 1 and Compound 2 results in the two compounds interacting on a molecular level. FIG. 14 depicts solid state 1H NMR spectra of a tablet comprising a blend of a spray dried dispersion of Compound 1 and a spray dried dispersion of Compound 2 at 70° C. and 75% relative humidity. The upper spectrum is the reference 1H NMR spectrum identifying the tablet components and the bottom spectrum is generated by cross polarization of the fluorine atom to protons on Compound 1 and spin diffusion between protons on Compound 1 and Compound 2 resulting in the growth of the Compound 2 peak. Surprisingly, molecular interaction between Compound 1 and Compound 2 exists in the blend at temperatures above the Tg as well as the co-spray dried dispersion substantially free of polymer.

D. Beneficial Properties of Spray Dried Dispersions of Amorphous APIs

The phenomena of one therapeutic agent having improved properties in the presence of another therapeutic agent is not limited to the neat co-spray dried dispersions substantially free of polymer previously described. This phenomena is demonstrated in the present embodiment of a blend of two individual spray dried dispersions. For example, Compound 1 has increased physical stability in a blend of a Compound 1 spray dried dispersion and a Compound 2 spray dried dispersion, as demonstrated in Tables 2 and 3. Table 2 lists the % crystallization of an 80% by weight SDD of Compound 1 over time at 80° C. at 75% relative humidity in the absence of Compound 2. Table 3 lists the % crystallization of Compound 1 in the presence of Compound 2 in a tablet of the present invention comprising a blend of Compound 1 SDD and Compound 2 SDD at 80° C. at 75% relative humidity.

TABLE 2 Time Crystallization (Hrs.) (%) 0 0 5.2 0 6 0 9 0.7 14.7 5 25 46.4 168 88

TABLE 3 Time Crystallization (Hrs.) (%) 0 0 7 3 14 6 21 8 26 10

At about 25 hours, 46% of Compound 1 crystallized in the absence of Compound 2, when only 10% of Compound 1 crystallized when Compound 2 was present.

This phenomenon of increased stability when one therapeutic agent is in the presence of another therapeutic agent is also demonstrated in the present embodiment where two therapeutic agents are co-spray dried from the same solvent. Referring to FIG. 9, the three sets of bar graphs on the far right demonstrate that the unexpected stability of Compound 1 in the presence of Compound 2 is not limited to the neat co-spray dried dispersion embodiment of Compound 1 and Compound 2, nor a blend of the two individual spray dried dispersions. The first of these sets of bars labeled Compound 1 SDD (50% HPMCAS) is a spray dried dispersion of Compound 1 and HPMCAS, without Compound 2. The remaining two sets of bars represent the concentration of Compound 1 within a co-spray dried dispersion of Compound 1, Compound 2, and a polymer. Comparing concentrations of Compound 1 in the bars labeled 1:1 coSDD (20% HPMCAS), which is a 1:1 ratio of Compound 1 to Compound 2 spray dried dispersion with HPMCAS, to those labeled Compound 1 SDD (50% HPMCAS), which is a spray dried dispersion of Compound 1 alone with HPMCAS, one can see that concentration stability is greater for Compound 1 over the 72 h when Compound 2 is present. Greater stability can also be seen in the 2:1 coSDD (20% HPMCAS) set of bars, which is a 2:1 ratio of Compound 1 to Compound 2 spray dried dispersion with HPMCAS, where the concentration of Compound 1 is more consistent than that in the Compound 1 spray dried dispersion (50% HPMCAS) formulation.

As with the neat co-spray dried dispersion of Compound 1 and Compound 2, the unexpected stability in FedSIF solutions in not limited to Compound 1. In FIG. 10, the first set of bars on the far right labeled Compound 2 SDD (20% HPMCAS) is a spray-dried dispersion Compound 2 and HPMCAS, without Compound 1. The remaining two sets of bars represent the concentration of Compound 2 within a co-spray dried dispersion of Compound 1, Compound 2, and polymer. Comparing concentrations of Compound 2 in the bars labeled 1:1 coSDD (20% HPMCAS), which is a 1:1 ratio of Compound 1 to Compound 2 spray dried dispersion with HPMCAS, to those labeled Compound 2 SDD (20% HPMCAS), which is a spray dried dispersion of Compound 2 alone with HPMCAS, one can see that concentration stability is greater for Compound 2 over the 72 h when Compound 1 is present. Greater stability can also be seen in the 2:1 coSDD (20% HPMCAS) set of bars, which is a 2:1 ratio of Compound 1 to Compound 2 spray dried dispersion with HPMCAS, where the concentration of Compound 2 is more consistent than that in the Compound 2 SDD (20% HPMCAS) formulation.

Without being bound by theory, when it comes to solvent systems, such as in vitro solvent systems as, for example, FedSIF, or in vivo solvent systems such as, for example, within a patient after ingesting Compound 1 prior to, subsequent to, or concurrently with Compound 2, the inventors submit that Compound 1 and Compound 2 act to impede the nucleation of each other. Such phenomena, sometimes referred to as poisoning nucleation, is unpredictable by structure.

IV. PHARMACEUTICAL COMPOSITIONS

Another aspect of the present invention provides a pharmaceutical composition comprising any of the spray dried dispersions or combinations of spray dried dispersions described above and a pharmaceutically acceptable vehicle, adjuvant, or carrier.

A. Pharmaceutically Acceptable Vehicles, Adjuvants, and Carriers

Remington: The Science and Practice of Pharmacy, 21st edition, 2005, ed. D. B. Troy, Lippincott Williams & Wilkins, Philadelphia, and Encyclopedia of Pharmaceutical Technology, eds. J. Swarbrick and J. C. Boylan, 1988-1999, Marcel Dekker, New York, the contents of each of which is incorporated by reference herein, disclose various carriers used in formulating pharmaceutically acceptable compositions and known techniques for the preparation thereof. Except insofar as any conventional carrier medium is incompatible with the compounds of the invention, such as by producing any undesirable biological effect or otherwise interacting in a deleterious manner with any other component(s) of the pharmaceutically acceptable composition, its use is contemplated to be within the scope of this invention.

In one embodiment, the pharmaceutical compositions of the present invention comprise a filler, a disintegrant, and a lubricant.

Fillers suitable for the invention are compatible with the ingredients of the pharmaceutical composition, i.e., they do not substantially reduce the solubility, the hardness, the chemical stability, the physical stability, or the biological activity of the pharmaceutical composition. Exemplary fillers include: celluloses, modified celluloses, (e.g. sodium carboxymethyl cellulose, ethyl cellulose hydroxymethyl cellulose, hydroxypropylcellulose), cellulose acetate, microcrystalline cellulose, calcium phosphates, dibasic calcium phosphate, starches (e.g. corn starch, potato starch), sugars (e.g., sorbitol) lactose, sucrose, or the like), or any combination thereof. In one embodiment, the filler is microcrystalline cellulose.

Thus, in one embodiment, the pharmaceutical composition comprises at least one filler in an amount of at least 5 wt % (e.g., at least about 20 wt %, at least about 30 wt %, or at least about 40 wt %) by weight of the composition. For example, the pharmaceutical composition comprises from about 10 wt % to about 60 wt % (e.g., from about 20 wt % to about 55 wt %, from about 25 wt % to about 50 wt %, or from about 27 wt % to about 45 wt %) of filler, by weight of the composition. In another example, the pharmaceutical composition comprises at least about 20 wt % (e.g., at least 30 wt % or at least 40 wt %) of microcrystalline cellulose, for example MCC Avicel PH102, by weight of the composition. In yet another example, the pharmaceutical composition comprises from about 10 wt % to about 60 wt % (e.g., from about 20 wt % to about 55 wt % or from about 25 wt % to about 45 wt %) of microcellulose, by weight of the composition.

Disintegrants suitable for the invention enhance the dispersal of the pharmaceutical composition and are compatible with the ingredients of the pharmaceutical composition, i.e., they do not substantially reduce the chemical stability, the physical stability, the hardness, or the biological activity of the pharmaceutical composition. Exemplary disintegrants include croscarmellose sodium, sodium starch glycolate, or a combination thereof. In one embodiment, the disintegrant is croscarmellose sodium.

Thus, in one embodiment, the pharmaceutical composition comprises disintegrant in an amount of about 10 wt % or less (e.g., about 7 wt % or less, about 6 wt % or less, or about 5 wt % or less) by weight of the composition. For example, the pharmaceutical composition comprises from about 1 wt % to about 10 wt % (e.g., from about 1.5 wt % to about 7.5 wt % or from about 2.5 wt % to about 6 wt %) of disintegrant, by weight of the composition. In another example, the pharmaceutical composition comprises about 10 wt % or less (e.g., 7 wt % or less, 6 wt % or less, or 5 wt % or less) of croscarmellose sodium, by weight of the composition. In yet another example, the pharmaceutical composition comprises from about 1 wt % to about 10 wt % (e.g., from about 1.5 wt % to about 7.5 wt % or from about 2.5 wt % to about 6 wt %) of croscarmellose sodium, by weight of the composition. In some examples, the pharmaceutical composition comprises from about 0.1% to about 10 wt % (e.g., from about 0.5 wt % to about 7.5 wt % or from about 1.5 wt % to about 6 wt %) of disintegrant, by weight of the composition. In still other examples, the pharmaceutical composition comprises from about 0.5% to about 10 wt % (e.g., from about 1.5 wt % to about 7.5 wt % or from about 2.5 wt % to about 6 wt %) of disintegrant, by weight of the composition.

In some embodiments, the pharmaceutical composition can include an oral solid pharmaceutical dosage form which can comprise a lubricant that can prevent adhesion of a granulate-bead admixture to a surface (e.g., a surface of a mixing bowl, a compression die and/or punch). A lubricant can also reduce interparticle friction within the granulate and improve the compression and ejection of compressed pharmaceutical compositions from a die press. The lubricant is also compatible with the ingredients of the pharmaceutical composition, i.e., they do not substantially reduce the solubility, the hardness, or the biological activity of the pharmaceutical composition. Exemplary lubricants include magnesium stearate, calcium stearate, zinc stearate, sodium stearate, stearic acid, aluminum stearate, leucine, glyceryl behenate, hydrogenated vegetable oil or any combination thereof. In embodiment, the lubricant is magnesium stearate.

Thus, in one embodiment, the pharmaceutical composition comprises a lubricant in an amount of 5 wt % or less (e.g., 4.75 wt %, 4.0 wt % or less, or 3.00 wt % or less, or 2.0 wt % or less) by weight of the composition. For example, the pharmaceutical composition comprises from about 5 wt % to about 0.10 wt % (e.g., from about 4.5 wt % to about 0.5 wt % or from about 3 wt % to about 1 wt %) of lubricant, by weight of the composition. In another example, the pharmaceutical composition comprises 5 wt % or less (e.g., 4.0 wt % or less, 3.0 wt % or less, or 2.0 wt % or less, or 1.0 wt % or less) of magnesium stearate, by weight of the composition. In yet another example, the pharmaceutical composition comprises from about 5 wt % to about 0.10 wt % (e.g., from about 4.5 wt % to about 0.15 wt % or from about 3.0 wt % to about 0.50 wt %) of magnesium stearate, by weight of the composition.

Pharmaceutical compositions of the invention can optionally comprise one or more colorants, flavors, and/or fragrances to enhance the visual appeal, taste, and/or scent of the composition. Suitable colorants, flavors, or fragrances are compatible with the ingredients of the pharmaceutical composition, i.e., they do not substantially reduce the solubility, the chemical stability, the physical stability, the hardness, or the biological activity of the pharmaceutical composition. In one embodiment, the pharmaceutical composition comprises a colorant, a flavor, and/or a fragrance.

In some embodiments, the pharmaceutical composition includes or can be made into tablets and the tablets can be coated with a colorant and optionally labeled with a logo, other image and/or text using a suitable ink. In still other embodiments, the pharmaceutical composition includes or can be made into tablets and the tablets can be coated with a colorant, waxed, and optionally labeled with a logo, other image and/or text using a suitable ink. Suitable colorants and inks are compatible with the ingredients of the pharmaceutical composition, i.e., they do not substantially reduce the solubility, the chemical stability, the physical stability, the hardness, or the biological activity of the pharmaceutical composition. The suitable colorants and inks can be any color and are water based or solvent based. In one embodiment, tablets made from the pharmaceutical composition are coated with a colorant and then labeled with a logo, other image, and/or text using a suitable ink. For example, tablets comprising pharmaceutical composition as described herein can be coated with about 3 wt % (e.g., less than about 6 wt % or less than about 4 wt %) of film coating comprising a colorant. The colored tablets can be labeled with a logo and text indicating the strength of the active ingredient in the tablet using a suitable ink. In another example, tablets comprising pharmaceutical composition as described herein can be coated with about 3 wt % (e.g., less than about 6 wt % or less than about 4 wt %) of a film coating comprising a colorant.

In another embodiment, tablets made from the pharmaceutical composition are coated with a colorant, waxed, and then labeled with a logo, other image, and/or text using a suitable ink. For example, tablets comprising pharmaceutical composition as described herein can be coated with about 3 wt % (e.g., less than about 6 wt % or less than about 4 wt %) of film coating comprising a colorant. The colored tablets can be waxed with Carnauba wax powder weighed out in the amount of about 0.01% w/w of the starting tablet core weight.

The tablets of the present invention can be produced by compacting or compressing an admixture or composition, for example, powder or granules, under pressure to form a stable three-dimensional shape (e.g., a tablet). As used herein, “tablet” includes compressed pharmaceutical dosage unit forms of all shapes and sizes, whether coated or uncoated.

Granulation and Compression

In some embodiments, solid forms, including powders comprising the active agents amorphous Compound 1 and amorphous Compound 2 and the included pharmaceutically acceptable excipients (e.g. filler, diluent, disintegrant, surfactant, glidant, binder, lubricant, or any combination thereof) can be subjected to a dry granulation process. The dry granulation process causes the powder to agglomerate into larger particles having a size suitable for further processing. Dry granulation can improve the flowability of a mixture to produce tablets that comply with the demand of mass variation or content uniformity.

Formulations as described herein may be produced using one or more mixing and dry granulations steps. The order and the number of the mixing and granulation steps do not seem to be critical. However, at least one of the excipients and amorphous Compound land amorphous Compound 2 can be subject to dry granulation or wet high shear granulation before compression into tablets. Dry granulation of amorphous Compound 1 and amorphous Compound 2 and the excipients made together prior to tablet compression seem, surprisingly, to be a simple, inexpensive and efficient way of providing close physical contact between the ingredients of the present compositions and formulations and thus results in a tablet formulation with good stability properties. Dry granulation can be carried out by a mechanical process, which transfers energy to the mixture without any use of any liquid substances (neither in the form of aqueous solutions, solutions based on organic solutes, or mixtures thereof) in contrast to wet granulation processes, also contemplated herein. Generally, the mechanical process requires compaction such as the one provided by roller compaction. An example of an alternative method for dry granulation is slugging.

In some embodiments, roller compaction is a granulation process comprising highly intensive mechanical compacting of one or more substances. In some embodiments, a pharmaceutical composition comprising an admixture of powders is pressed, that is roller compacted, between two counter rotating rollers to make a solid sheet that is subsequently crushed in a sieve to form a particulate matter. In this particulate matter, a close mechanical contact between the ingredients can be obtained. An example of roller compaction equipment is Minipactor® a Gerteis 3W-Polygran from Gerteis Maschinen+Processengineering AG.

In some embodiments, tablet compression according to the invention can occur without any use of any liquid substances (neither in the form of aqueous solutions, solutions based on organic solutes, or mixtures thereof), i.e., a dry granulation process. In a typical embodiment the resulting core or tablet has a compressive strength in the range of from about 1 kp to about 15 kP; such as 1.5 to 12.5 kP, preferably in the range of 2 to 10 kP.

Brief Manufacturing Procedure

In some embodiments, the ingredients are weighed according to the formula set herein. Next, all of the intragranular ingredients are sifted and mixed well. The ingredients can be lubricated with a suitable lubricant, for example, magnesium stearate. The next step can comprise compaction/slugging of the powder admixture and sized ingredients. Next, the compacted or slugged blends are milled into granules and sifted to obtain the desired size. Next, the granules can be further lubricated with, for example, magnesium stearate. Next, the granular composition of the invention can be compressed on suitable punches into various pharmaceutical formulations in accordance with the invention. Optionally the tablets can be coated with a film, colorant or other coating.

Another aspect of the invention provides a method for producing a pharmaceutical composition comprising an admixture of a composition comprising amorphous Compound 1 and amorphous Compound 2 and one or more excipients selected from: a filler, a diluent, a binder, a glidant, a surfactant, a lubricant, a disintegrant, and compressing the composition into a tablet having a dissolution of at least about 50% in about 30 minutes.

In another embodiment, a wet granulation process is performed to yield the pharmaceutical formulation of the invention from an admixture of powdered and liquid ingredients. For example, a pharmaceutical composition comprising an admixture of a composition comprising amorphous Compound 1 and amorphous Compound 2 and one or more excipients selected from: a filler, a diluent, a binder, a glidant, a surfactant, a lubricant, a disintegrant, are weighed as per the formula set herein. Next, all of the intragranular ingredients are sifted and mixed in a high shear or low shear granulator using water or water with a surfactant or water with a binder or water with a surfactant and a binder to granulate the powder blend. A fluid other than water can also be used with or without surfactant and/or binder to granulate the powder blend. Next, the wet granules can optionally be milled using a suitable mill. Next, water may optionally be removed from the admixture by drying the ingredients in any suitable manner. Next, the dried granules can optionally be milled to the required size. Next, extra granular excipients can be added by blending (for example a filler, a diluent, and a disintegrant). Next, the sized granules can be further lubricated with magnesium stearate and a disintegrant, for example, croscarmellose sodium. Next, the granular composition of the invention can be sifted for sufficient time to obtain the correct size and then compressed on suitable punches into various pharmaceutical formulations in accordance with the invention. Optionally, the tablets can be coated with a film, colorant or other coating.

Each of the ingredients of this exemplary admixture is described above and in the Examples below. Furthermore, the admixture can comprise optional additives, such as, one or more colorants, one or more flavors, and/or one or more fragrances as described above and in the Examples below. In some embodiments, the relative concentrations (e.g., wt %) of each of these ingredients (and any optional additives) in the admixture are also presented above and in the Examples below. The ingredients constituting the admixture can be provided sequentially or in any combination of additions; and, the ingredients or combination of ingredients can be provided in any order.

In another embodiment, the admixture comprises a composition of amorphous Compound 1 and amorphous Compound 2, and any one or more of the excipients; a binder, a glidant, a surfactant, a diluent, a lubricant, a disintegrant, and a filler, wherein each of these ingredients is provided in a powder form (e.g., provided as particles having a mean or average diameter, measured by light scattering, of 250 μm or less (e.g., 150 μm or less, 100 μm or less, 50 μm or less, 45 μm or less, 40 μm or less, or 35 μm or less)). For instance, the admixture comprises a composition of amorphous Compound 1 and amorphous Compound 2, a diluent, a glidant, a surfactant, a lubricant, a disintegrant, and a filler, wherein each of these ingredients is provided in a powder form (e.g., provided as particles having a mean diameter, measured by light scattering, of 250 μm or less (e.g., 150 μm or less, 100 μm or less, 50 μm or less, 45 μm or less, 40 μm or less, or 35 μm or less)). In another example, the admixture comprises a composition of amorphous Compound 1, amorphous Compound 2, a diluent, a binder, a surfactant, a lubricant, a disintegrant, and a filler, wherein each of these ingredients is provided in a powder form (e.g., provided as particles having a mean diameter, measured by light scattering, of 250 μm or less (e.g., 150 μm or less, 100 μm or less, 50 μm or less, 45 μm or less, 40 μm or less, or 35 μm or less)).

In another embodiment, the admixture comprises a composition of amorphous Compound 1, amorphous Compound 2 and any combination of: a binder, a glidant, a diluent, a surfactant, a lubricant, a disintegrant, and a filler, wherein each of these ingredients is substantially free of water. Each of the ingredients comprises less than 5 wt % (e.g., less than 2 wt %, less than 1 wt %, less than 0.75 wt %, less than 0.5 wt %, or less than 0.25 wt %) of water by weight of the ingredient. For instance, the admixture comprises a composition of amorphous Compound 1, amorphous Compound 2, a diluent, a glidant, a surfactant, a lubricant, a disintegrant, and a filler, wherein each of these ingredients is substantially free of water. In some embodiments, each of the ingredients comprises less than 5 wt % (e.g., less than 2 wt %, less than 1 wt %, less than 0.75 wt %, less than 0.5 wt %, or less than 0.25 wt %) of water by weight of the ingredient.

In another embodiment, compressing the admixture into a tablet is accomplished by filling a form (e.g., a mold) with the admixture and applying pressure to admixture. This can be accomplished using a die press or other similar apparatus. In some embodiments, the admixture of amorphous Compound 1, amorphous Compound 2, and excipients can be first processed into granular form. The granules can then be sized and compressed into tablets or formulated for encapsulation according to known methods in the pharmaceutical art. It is also noted that the application of pressure to the admixture in the form can be repeated using the same pressure during each compression or using different pressures during the compressions. In another example, the admixture of powdered ingredients or granules can be compressed using a die press that applies sufficient pressure to form a tablet having a dissolution of about 50% or more at about 30 minutes (e.g., about 55% or more at about 30 minutes or about 60% or more at about 30 minutes). For instance, the admixture is compressed using a die press to produce a tablet hardness of at least about 5 kP (at least about 5.5 kP, at least about 6 kP, at least about 7 kP, at least about 10 kP, or at least 15 kP). In some instances, the admixture is compressed to produce a tablet hardness of between about 5 and 20 kP.

In some embodiments, tablets comprising a pharmaceutical composition as described herein can be coated with about 3.0 wt % of a film coating comprising a colorant by weight of the tablet. In certain instances, the colorant suspension or solution used to coat the tablets comprises about 20% w/w of solids by weight of the colorant suspension or solution. In still further instances, the coated tablets can be labeled with a logo, other image or text.
